Abstract: Agro-biogas mode has diversified types and low benefit, and its current research has the problem of one-sidedness. We analyzed the whole industrial chain of agro-biogas mode by using 6 typical cases with different scales, breeding types and biogas fertilizer utilization methods in Shandong. The results clarified the structure, function and deficiency of the mode, indicated its relationship with environment and resource, revealed the technical bottleneck for the mode’s application and found 4 key factors to fulfill the good operation of mode; also we presented an optimized program according the scale matching of planting-breedingbiogas, circular chain extending, resource value increase and circular path shortening. The optimal mode should meet some key conditions, including the technology for appropriate utilization of biogas fertilizer and environmental safety, breaking the boundary between agriculture, livestock and biogas engineering, improving compensation and distribution mechanisms, thus to realize the dynamic integration of planting and breeding industry.
